New Zealand coastal harvest waters

Before a single mussel is harvested, the water itself must pass. New Zealand's Ministry for Primary Industries (MPI) — the government agency that sets and enforces the country's food safety, fisheries, and biosecurity standards — conducts mandatory weekly tests on both water samples and shellfish from all harvest areas. This program monitors for biotoxins (including paralytic shellfish toxins), harmful algal bloom indicators, and microbial contamination. Because it is a government-mandated program and not something we commission, there is no conflict of interest. If the water fails, the harvest doesn't happen.

Independent government oversight — no conflict of interest

After CO₂ supercritical extraction

GLX3 uses supercritical CO₂ extraction — a clean, solvent-free process that preserves the natural fatty acid profile without chemical residues common in cheaper hexane-based methods. Once the raw oil is produced, it is immediately tested for the full contamination panel. Nothing moves forward until this comes back clean.

Heavy metals — lead, mercury, arsenic & cadmium

Oxidation markers — peroxide value & TOTOX score

Applied to every raw material entering the formula

The Ministry for Primary Industries (MPI) is New Zealand's government agency responsible for the safety, sustainability, and integrity of the country's food, fisheries, and agricultural supply chain. It sets and enforces the standards that govern what can be harvested, processed, and exported — with the legal authority to halt any part of the supply chain that doesn't comply. Under MPI regulations, it's not just the mussel oil that must be verified — every raw ingredient entering the GLX3 formula must be independently tested and approved before it can be used. No exceptions.

Each of the four ingredients below was chosen deliberately — not just for what it contributes to the formula, but for what it replaces: synthetic fillers, chemical binders, and artificial preservatives.

Cold-pressed olive oil — olive oil's role in GLX3 goes far beyond being a carrier. It is rich in polyphenols — plant-based compounds that meaningfully enhance the bioavailability of omega-3 fatty acids. Polyphenols help protect the omega-3s from oxidation during digestion, keeping them intact and active so your body can actually absorb and use them. Research suggests that combining omega-3s with olive oil polyphenols improves their uptake compared to omega-3s delivered alone. It also acts as a natural stabilizer for the oil blend, eliminating any need for synthetic binders or fillers.

Vitamin E oil (from sunflower) — a natural tocopherol sourced exclusively from sunflower, not synthesized in a lab. Its job is to protect the omega-3 oil from oxidation both during production and over the product's shelf life. Because it does this job effectively on its own, there is no need for chemical preservatives or artificial antioxidants anywhere in the formula.

Bovine gelatin capsule — the softgel shell itself is tested as a raw material. GLX3 uses a bovine (beef-derived) gelatin capsule, which undergoes the same independent purity screening as every other input. Bovine gelatin produces a clean, reliable encapsulation without the chemical softeners or plasticizers found in some synthetic capsule alternatives.

Finished product after full encapsulation

Once the oil is sealed into its final softgel form, the finished product is sent to Eurofins — one of the most respected independent analytical testing organisations on earth. Operating 900+ laboratories across 60+ countries and holding ISO/IEC 17025 accreditation, Eurofins serves pharmaceutical, food safety, and nutraceutical industries globally. Their testing confirms the product you receive matches exactly what's on the label. Most brands stop here — if they test at all.

Final glass-bottled product · Imported to the USA

After the finished product arrives in the US in its final glass bottle, it is tested one more time — by LightLabs, a consumer-focused testing lab known for making science legible to everyday people. Their reports are written in plain English with clear, unambiguous pass/fail results. No chemistry degree required. No buried footnotes. Just the truth about what's in the bottle you're buying.

Publicly available. Every LightLabs report is easily available — no account, no email required.  That's not just transparency — that's accountability you can hold in your hands.
